Rankl expression predicts poor prognosis in gastric cancer patients: results from a retrospective and single-center analysis

Braz. j. med. biol. res; 51 (3), 2018
The receptor activator of nuclear factor κB ligand (RANKL)/RANK pathway plays an important role in the prognosis of several solid tumor types, but its role in gastric cancer prognosis has been poorly characterized. A total of 116 gastric cancer patients who underwent surgical resection were enrolled...

Improving adenoviral vectors and strategies for prostate cancer gene therapy

Clinics; 73 (supl.1), 2018
Gene therapy has been evaluated for the treatment of prostate cancer and includes the application of adenoviral vectors encoding a suicide gene or oncolytic adenoviruses that may be armed with a functional transgene. In parallel, versions of adenoviral vector expressing the p53 gene (Ad-p53) have been te...

Evidence of progenitor cells in the adult human cochlea: sphere formation and identification of ABCG2

Clinics; 72 (11), 2017
OBJECTIVES: The aim of this study was to search for evidence of stem or progenitor cells in the adult human cochlea by testing for sphere formation capacity and the presence of the stem cell marker ABCG2. METHODS: Cochleas removed from patients undergoing vestibular schwannoma resection (n=2) and from b...

Tumor del estroma gastrointestinal y trasplante renal
Gastrointestinal stromal tumor and renal transplant

Medicina (B.Aires); 77 (4), 2017
El tumor estromal gastrointestinal (GIST) representa alrededor del 1% de todos los tumores digestivos y su aparición en pacientes trasplantados renales es infrecuente. Aproximadamente el 95% muestra tinción positiva para c-kit/CD117. DOG1 es un anticuerpo recientemente descrito que se sobre-expresa en ...

Iodine-131 treatment of thyroid cancer cells leads to suppression of cell proliferation followed by induction of cell apoptosis and cell cycle arrest by regulation of B-cell translocation gene 2-mediated JNK/NF-kappaB pathways

Braz. j. med. biol. res; 50 (1), 2017
Iodine-131 (131I) is widely used for the treatment of thyroid-related diseases. This study aimed to investigate the expression of p53 and BTG2 genes following 131I therapy in thyroid cancer cell line SW579 and the possible underlying mechanism. SW579 human thyroid squamous carcinoma cells were cultured a...

Ki-67 protein predicts survival in oral squamous carcinoma cells: an immunohistochemical study

Abstract The aim of this study was to identify the expression of Ki-67 and MCM3 in oral squamous cell carcinoma (OSCC) as well as to address the correlation with patient survival and clinical features. Samples were collected from 51 patients with OSCC who presented for follow-up. Immunohistochemical expr...

Programmed cell death 5 transgenic mice attenuates adjuvant induced arthritis by 2 modifying the T lymphocytes balance

Biol. Res; 50 (), 2017
BACKGROUND: Programmed cell death 5 (PDCD5) is an apoptosis-related gene cloned from TF-1 cells whose primary biological functions are to promote apoptosis and immune regulation. The effects and mechanisms exerted by key mediators of arthritic inflammation remain unclear in PDCD5 transgenic (PDCD5 tg) mi...

Efecto de las alteraciones genéticas y epigenéticas de la cadherina E y su expresión en la transcripción en la propensión al cáncer de mama

Biomédica (Bogotá); 36 (4), 2016
RESUMEN Introducción. La cadherina E (CDH1) cumple un papel importante en la transición epitelio-mesénquima y está relacionada con la invasión y las metástasis en varios tipos de carcinomas. Sin embargo, el efecto de las mutaciones y 'epimutaciones' germinales en la propensión al cáncer de mama ...

The destruction complex of beta-catenin in colorectal carcinoma and colonic adenoma

Einstein (Säo Paulo); 14 (2), 2016
ABSTRACT Objective To evaluate the destruction complex of beta-catenin by the expression of the proteins beta-catetenin, adenomatous polyposis coli, GSK3β, axin and ubiquitin in colorectal carcinoma and colonic adenoma. Methods Tissue samples from 64 patients with colorectal carcinoma and 53 pat...

TGF-β1 expression is associated with invasion and metastasis of intrahepatic cholangiocarcinoma

Biol. Res; 48 (), 2015
BACKGROUND: Transforming growth factor (TGF)-β is involved in many physiologic processes, it often promotes metastasis, and its high expression is correlated with poor prognosis. In the present study, we analyzed the correlation between transforming growth factor beta 1 (TGF-β1) expression and prognosi...
